SPECIFICATION forming part of Letters Patent No.

276,880, dated May 1, 1883.

Application filed July 15, 1882. (Nd model.)

To all whom it may concern:

Be it known that I, THOMAS 8.11am). of Bridgeport, in the county ofFairfield and State of Connecticut, have invented a'certain new anduseful Improvement in Electrical Conductors, of which the following isaspeei iication.

My improvement relates to the flexible electrieal conductors which arecommonly used in conjunction with telephonereceivers,and with variousanalogous articles requiring to be moved'from place to place. Suchelectrical conductors have commonly been made of very fine, delicateWires enveloped in a braided covering. r

The principal object of my invention is to providtran electricalconductor, (or use in conneetion with telephones, which will notbellable to kink and become tangled when slackened, and in which theline, delicate wires shall not be liable to injury because of thestretching of their covering, as a braided covering will do.

The improvement consists in a new article of manut'acture namely, an.electrical conductor-consisting of a. number of fine metal wires orfilaments laid side by side in approximately the same plane, and a fiatfabric incasing the 'same, and having longitudinal threads incorporatedinto it and serving as longitudinal stays or braces.

In the accompanying drawings, Figure l is a partly-sectional side view01' an electrical conductor embodying my lillplOVGlllQllt, and Fig. 2is'a sectional view of a tip which is ap plied to the ends of itsbranches.

Similar letters of reference designate corresponding parts in bothfigures.

A designates a number of fine metal wires or filaments, made, forinstance, of copper or brass. Preferably I use what is termed tinsol, anarticle consisting of a thread having a llat metal wi're or filamentwound spirally around it, as this is susceptible of being bent andstretched a greatd eal without breaking.

B designates a covering made in the form fabric and enveloping the wiresA. It may he made of cotton or other suitable material,and-may be woven.In any case it will have longitudinal or warp threads incorporated intoit for preventing it from stretchin". This may be woven or formed overor upon the wires A; or it maybe made in the form of a pocket into whichthe wires may be slipped; or, indeed, it may be made in a flat fabricand sewed around the wires.

It desirable for-any special purposes, indiarubber cloth oranalogousmaterial may incase the wires A and be surrounded by the covering.: Near the, ends the covering is divided longitudinally to form twobranches each con tainiug halt the wires. This may be done in themanufacture of the covering, or itanay be manufactured in one continuousand uniform piece, to be subsequently cut and sewed to form thebranches. The wires are laid side by side in approximately the sameplane, and at the ends of the branches have attached to them pins 0,which are adapted to be inserted and secured in the binding'posts ot'telephone-receivers or other articles.

To impart a finished appearance to the ends of the branches I preferablyincase them in tips of sheet metal, l). These tips will prefer ably bemade oi two sections, having, their edges overlapped so as to securethem together. The pins 0 pass through semicircular recesses i'ormcd inthese sections of the tips.

What i claim as my invention, and desire to secure by Letters Patent,is-

As a new article of manufacture, an electii. cal conductor, consistingof a number of line metal wires or filaments laid side by side inapproximately the same plane, and a Hat fabric iucasing the same, andhaving threads incorporated into it and serving as longitudinal stays orbraces, substantially as and for the purpose herein described.
